MACHINERY FOR PRODUCING STITCH-HOLES.

SPECIFICATION forming part of Letters Patent No. 270.909, dated January 23, 1883,

Application filed November 10, 1882. (No model.)

To all whom "it may concern Be it known that I, EDWIN F. MOWER, of Boston, in the'county of Suffolk and State of Massachusetts,'have invented a new and use- 5 ful Improvement in Machinery for Producing Stitch-Holes in the Insoles of Boots or Shoes; and I do hereby declare the same to be described in the following specification and represented in the accompanying drawing, which to is a side view of such mechanism and a transverse section of an insole, showing in dotted lines the curved puncturing-awl extending through it for the purpose of forming a stitchhole in it.

15 The nature of my invention is defined in the claim hereinafter presented.

In such drawing, Arepresents an awl curved near its point in manner as shown at a, it being projected from the lower end of a lever,

20 B, shaped as shown, and provided with acyliu'drical fulcrum-stud, a, extended from it into a curved slot, 12, made, as represented, in a stationary bracket, 0. The lever at its upper end is jointed to an, arm, D, to which recipro- 2 5' eating motions vertically are to be imparted by any suitable mechanism,in order that similar motions may be imparted to such lever. While the lever is being so moved it will not only be caused to move upward and downward, but forward and backward, so as to force the 0 awl laterally into and through the sole in a direction to cause a stitch-hole to be formed therein through its edge and inclined therefrom to the outer surface of the sole. Byproperly moving the sole while the awl is out of it 5 such sole may be brought into the required positions fora series of stitch-holes to be formed in and around it, as they are usually madeby a workman with an awl held in his hand.

I claim The combinationof the lever, the curved awl, and the fulcrum or stud arranged with such lever, as described, with the stationary bracket having in it the curved slot to receive the said stud or fulcrum, such lever being 5 adapted to be moved upward and downward, all substantially as and for the purpose set forth.

EDWIN F. MOWER.
